Title: Improvements in or relating to balls for sport
IPC: A63B41/08
Filed: 1933-11-28
Abstract: A ball cover, for example, a football casing, is made partly or wholly of a rubber mix compounded with wood in the form of long fibres, such as wood-wool or masticated wood shavings, which is then vulcanized.  Preferably the compound is coated, for example, calendered, on to a fabric such as canvas, cut on the cross to give resilience, and vulcanized thereon, the cover being formed by pieces of coated fabric stitched together.  Alternatively, the compound may be moulded on to a reinforced bladder, which is then inflated to force the cover against an outer mould, the cover then being cured. In another method, the compound is applied to the roughened surface of a leather casing of less than normal thickness and then cured. Alternatively, shaped pieces, formed according to the first method described above, may be cemented to the leather casing, or such cured pieces may be applied to depressions in various parts of the leather casing.  The wood-wool prior to being compounded with the rubber and fillers may be proofed with material such as casein.

Title: Shuttleless winding machine for toroidal magnetic cores
Inventor: HASKOVEC JIRI
IPC: H01F41/08
Filed: 1961-09-16
Abstract: 911,622. Winding toroidal cores. CESKO. SLOVENSKA AKADEMIE VED NO.3. Sept. 16, 1961, No. 33289/61. Class 83 (4). A shuttleless winding-machine for toroidal magnetic cores, in which the wire to be wound on the core is carried by two supporting rollers, the supply bundle of such wire passing only through the opening in the toroidal core, ineludes a movable pick-up roller, adjacent the supporting rollers, which serves for picking up the wire from the supply bundle by engaging the wire during its movement and taking it off both supporting rollers in succession, whereupon after the wire has slipped off the pick-up roller the latter passes outside the opening in the toroidal core back to its initial position, a separating member provided in the opening of the toroidal core being intended to separate the wire of the completed turn from the supply bundle. Wire 1 is first wound over rollers 2 and 3 to run through an annular core 4. The end of the wire is then secured to the core 4. A roller 6, on the end of a lever 8 moved by crank means 9, 10, then moves in a double elliptical path so that a wire strand, separated from bundle passing over the rollers 2, 3 by a finger 5 extending through the core 4, is taken off the roller 2 and then off the roller 3 by the roller 6 which thus lays it around the outside of the core. The roller 2 is driven through a slipping clutch 16 to maintain tension in the wire and, as the wire slips off the roller 6 at 19, to pull it through the core 4. A pair of resilient clamp members 7, Fig. 6, prevent slackening of turns already wound. The turns may be counted.

Title: Polysulphide rubber and method of making the same
IPC: C08G75/16
Filed: 1960-09-29
Abstract: Rubbery polysulphides are prepared by reacting alkali-metal polysulphides with a -o  dihalides of the formula C12H24X2 where the C12H24 group is a branched chain.  The dihalide used is a mixture of isomers prepared by the action of haloacids on the glycols of U.S.A. Specification 2,850,538, [Group IV(b)] and a typical mixture is 33% linear C12 a -o  dihalide, 55% ethyl substituted C10 a -o  dihalide, and 15% diethyl substituted C8 a -o  dihalide.  This mixture may be used per se, but preferably the linear isomer is removed by recrystallization.  Higher pressures (up to 500 p.s.i.) and temperatures (100 DEG -200 DEG C.) than usual are necessary to carry out the reaction.  In order to cross-link the polymer, a small amount of 1,2,3-trichloropropane may be added.  In the examples, methanol is present during the reaction, and Nekal and Mg(OH)2 (formed in situ) are used as dispersants, and the latex first produced is hardened by washing with water and reaction with further polysulphide, followed by a further washing and reaction with polysulphide.  The reaction is carried out under nitrogen in Example 2.ALSO:The mixture of C12 saturated glycols prepared according to U.S.A.  Specification 2,850,538 is converted to the dihalides by reaction with hydrohalogen acids and excess acid and water distilled off.  A typical product is 30% linear a -o  C12 dihalide, 55% ethyl substituted C10 a -o dihalide, and 15% diethyl substituted C8 a -o  dihalide.  The linear C12 dihalide may be removed by recrystallisation.
